This upgrades Review Board's JavaScript test suite to use Jasmine 3.5

instead of the very old 2.4.1. This version provides many new features

and fixes over 2.4.1, such as:

New spy functionality:

Spying on promises and on properties
Spying on all functions on an object
Creating selective spies that execute only for specific arguments
Setting a default spy strategy (call fake, call original, etc.) for

  all spies in a suite).


Better assertion matchers:

toBeFalse()
toBeTrue()
toBeInstanceOf()
toHaveBeenCalledBefore() (ensuring one spy is called before

  another spy)
toHaveClass() (for checking CSS classes on elements)
Plus others


Fixes for equality comparison for arrays and objects
Utilities for better comparing arrays and objects in a variety of ways

  (treating arrays like sets, or comparing subsets of objects)
Improved ES6 support (maps, async functions, properties)
Better error output (improved stack traces, value diffing)
Running tests in random order to check for interdependencies

All tests continue to pass. They don't pass if using random orders,

which is normally the default, but we've disabled that by default for

our test runs.
All existing functionality (including or custom additions) continue to

work as before. There are some differences in the display of tasks that

have run, but they mostly amount to color changes and the display of

little indicators to show successful/failed tests.

All JavaScript unit tests pass.
